At the scale of individual cells, the human body is constantly in motion. Every second, millions of cells divide, ...

Chemically induced skin tumors arise from long-lived stem cells of the upper hair follicle Evolution continuously forges new biological innovations written in genomes. Navigating this vast design ...

Modern humans carry DNA from two mysterious extinct lineages in addition to Neanderthals and Denisovans. Their hidden genetic legacy shows that our evolutionary past was shaped by repeated mixing ...

Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by DNA damage. Among the most dangerous lesions are DNA interstrand crosslinks ...

Thymine metabolism in prokaryotes encompasses both de novo synthesis of deoxythymidine triphosphate (dTTP) via the reductive branch of pyrimidine biosynthesis and salvage pathways that recover ...

This study is reported by Guojun Wang’s group from the College of Life Sciences, Inner Mongolia University, Hohhot, China. Bovine Parainfluenza Virus Type 3 (BPIV3) is a leading cause of respiratory ...

In the oceans and on land, scientists are discovering rare, transitional organisms that bridge the gap between Earth’s simplest cells and today’s complex ones. By Carl Zimmer A flurry of new studies ...

AlphaGenome is a leap forward in the ability to study the human blueprint. But the fine workings of our DNA are still largely a mystery. By Carl Zimmer In 2024, two scientists from Google DeepMind ...

DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave. Researchers have now mapped this hidden architecture in unprecedented detail, showing ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...

Human history is rife with contentions about the purity (and superiority) of the bloodlines of one group over another and claims over ancestral homelands. More than a decade of work on ancient human ...
